Subject: shortlog: warn the user when there is no input
X-Git-Tag: v1.7.1-rc0~85^2
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=3731449591130b2f5ca7257c46721785a6340a18;p=git.git

shortlog: warn the user when there is no input

A simple "git shortlog" outside of a git repository stalls
waiting for an input. Check if that's the case by testing with
isatty() before read_from_stdin(), and warn the user like
"git commit" does in a similar case.
